How To Remove Hard Water Spots

Hard water spots on car paint

Water sprinklers attack your car? Nothing can be more aggravating since hard water spots can seem hard to remove. Don't worry, there is a solution but the key is to treat the issue as soon as possible.

 

What You'll Need:



Time is of the essence. Removing the hard water spots immediately after it has happened is going to be a lot easier than trying to remove it after it's been allowed to sit in the hot sun for hours or days.

The problem with hard water is that it has minerals that etch into the surface of your car's paint finish making it hard to remove with a simple wash.

 

Solution

Step 1

Wash the car thoroughly. This will remove road grime and dust on your car. It will also help eliminate some of the minerals responsible for the hard water spots. As always, wash in a shaded location - never in direct sunlight. While the products we are going to use are completely safe to use, heat from a hot surface or direct sunlight can turn something harmless like car soap into an amplified cleaner which can yield unknown results. So while vinegar is completely safe to use on your car's surface, using it in hot sun should be avoided. Now dry the car completely. Read how to correctly wash and dry your car.


Step 2

Mix 1 part regular white vinegar with 1 part distilled water. It's better not to use regular tap water which contains minerals. Apply the vinegar/water solution with a spray bottle on to the affected paint finish. Allow mixture to work for up to 10 minutes. The acid in the vinegar will help loosen the hard water minerals embedded in the paint. This is similar to running your coffee maker with vinegar to remove the build up of hard water.

After allowing to work for 10 minutes, wash and dry the car again to remove the water/vinegar solution. The minerals from the hard water will be gone at this point but you may still notice the rings. If so, go on to the next step.

 

Step 3

Polish the surface with einszett Paint Polish and a plush cotton towel (do not use bulk towels, rags, cloth diapers or flannel) or apply with a Dual Action Orbital machine using a polishing pad and set on medium. After polishing the surface, buff off the area with a microfiber towel. Repeat the process if necessary. Several passes might be required in order to completely remove the hard water spots.

Paint Polish has special abrasives that will reduce the appearance of the etch marks left by the hard water. It can also remove unsightly swirl marks from your paint. After application, not only will the hard water spots be removed but your paint will look like it did the day you bought the car.

Step 4

In order to dramatically reduce the harm hard water has on your car's paint finish in the future, apply a coat of einszett Glanz Wax on the polished surface to protect and seal the finish. Glanz Wax, with its long-lasting synthetic waxes, helps protect against hard water as well as road grime, sap, bird droppings and UV rays. Having a protective layer of Glanz Wax is like having a shield around your paint finish. The next time water sprinklers spray all over your car, Glanz Wax will greatly reduce the hard water's ability to penetrate your paint finish buying you time to wash it off.


Summary

The key to removing hard water spots is to not let it stand too long. Especially in hot summer months. With a coating of Glanz Wax on your paint finish, you'll buy yourself some time to wash the hard water away as soon as possible.

We also recommend carrying a bottle of Waterless Wash and a Microfiber Towel with you in your car in case you find it's been attacked by rogue sprinklers or even bird droppings. A simple spray and wipe down will take care of the issue immediately before it become a problem.
